Overview

Health begins in our communities. Exploring information about the diversity of our communities is a starting point to ask questions about the health and wellbeing of people across the population. These community profiles allow you to explore data that describe the composition of the municipalities across CHA’s primary service area.

Navigate to each topic area using the Table of Contents on the left-hand side of this page. All data used in this analysis are from the U.S. Census Bureau’s American Community Survey (ACS) 2015-2019 five-year estimates. For each topic area, the corresponding ACS table is cited, and can be explored directly on data.census.gov. This analysis was carried out using R statistical software, with key packages including tidyverse and tidycensus.  

Age and Sex Structure

The age and sex structure of a community refers to how the population is distributed across age ranges, for males and for females. In the table below, use the filters to find specific values of interest, or to sort by a variable of interest. In the interactive graphs, the percentage of residents who are male or female within each age category are displayed for each community. Hover over the bars to see the percentage value and the total number (estimate) of residents in each group. The total population of the city is displayed as well. Source: ACS Table B01001

Racial and Ethnic Composition

There are many way to explore the racial and ethnic composition of a community. In the table below, use the filters to find specific values of interest, or to sort by a variable of interest. There are three sets of interactive graphs that follow. In the first set, the percentage of residents who identify their ethnicity as Hispanic vs. non-Hispanic are displayed. In the second set, the percentage of Hispanic residents who identify with each racial group are displayed. In the third set, the percentage of residents who identify with each racial and ethnic group combination are displayed. Hover over the bars to see the percentage value and the total number (estimate) of residents in each group. Source: ACS Table B03002

Countries of Origin

To describe the diversity of immigrant communities in CHA’s service area, the percentage of residents who were born in a country outside of the U.S. is shown below, followed by a set of visualizations showing the most common countries of origin among the foreign-born population in each city. After the most common single countries of origin were calculated, all other countries of origin were grouped together. Color coding denotes the region of origin, with colors consistent across each city. Source: ACS Table B05006

Languages Spoken at Home

To describe the diversity of languages spoken in CHA’s service area, several visualizations are provided. The first visualization displays the percentage of residents who speak only English, compared to those who speak another language or more than one language. The second set of visualizations displays the most common languages spoken among residents who do not speak only English in each city. The ACS provides estimates for some single languages (for example, Spanish, Korean, Arabic), but only grouped estimates for others (for example, Other Indo-European Languages, which includes Portuguese). After the most common single languages or language groups were calculated, all other non-English languages or language groups were grouped together. The third set of visualizations displays the percentage of residents who speak English “very well” or “less than very well” within each non-English language group. Source: ACS Table C16001

Education

This section explores the distribution of residents in each city by highest level of education completed. The population for this section includes only residents older than 25 years of age. In the table below, use the filters to find specific values of interest, or to sort by a variable of interest. In the interactive graph, the percentages of residents (over age 25) who have completed each level of education are displayed for each community. Hover over the bars to see the percentage value of residents in each group. Source: ACS Table B07009

Household Type

This section explores the composition of households in each city. In the table below, use the filters to find specific values of interest, or to sort by a variable of interest. There are two sets of interactive graphs that follow. In the first set, the percentage of households that are considered “family” versus “non-family” are displayed. In the second set, the percentage of households of different sizes within “family” and “non-family” households are displayed. Source: ACS Table B11016
